[ID: 297] Gleon DOM seasons
PI: Andrew Tanentzap
Dissolved organic matter (DOM) is central to the functioning of lakes, but its molecular composition remains a “blackbox” at large spatial and temporal scales. This project aims to understand how the origin and composition of DOM varies through time using ultra-high-resolution mass spectrometry and its association with biogeochemical data collected from high-frequency sensors (e.g. dissolved oxygen, chlorophyll a, fDOM/CDOM). We are interested in collecting surface water samples at a monthly interval for 1 year from the deepest point in your study lakes. We will process all samples using a standardized protocol and make data freely available for reuse on a cloud server. Sampling will run between Jan 2021 and Dec 2021 with standardized consumables.
